DC electric motors of the series 4PFM112, 132, 160, 180
The electric motors are designed for adjustable electric drives of various mechanisms, including electric drives of metal cutting machines.
Electric motor power can be used both from direct current generators and from rectifier devices.
Designation
4xxx xVHO2 O4:
4 - serial number of the series;
P - DC electric motor with a tachogenerator and heat protection sensors;
F - secure execution with independent ventilation;
Xxx - the height of the axis of rotation, mm (112, 132, 160, 180);
X is the conditional length of the anchor: S-first length, m-second length, L-three length, fourth length, n-fifth length;
B - the presence of a filter, without a letter - lack of a filter;
X - fan position: B - location of the fan on the side surface of the electric motor (left, right, from above); T - the location of the fan on the end surface of the electric motor from the collector side;
02 - with a place equipped for installing a measuring photoelectric transducer; Without designation - the lack of space for the transducer of the measuring photoelectric;
04 - climatic execution and category of accommodation according to GOST 15150-69.
Design
Widely-regulated, with a completely sewed stator, integral poles, compensatory winding, insulation of the heating resistance class F according to GOST 8865-87, increased accuracy, with an attached TP80-20-0.2 tachogenerator and heat protection sensors with independent ventilation from an attached electric fan,, with an attached electric fan IP23S protection degree in accordance with GOST 17494-87, method of cooling IC06 according to GOST 20459-87.
The excitation of electric motors is independent, excitation voltage 220 or 110 V.
Constructive performance according to the installation method according to GOST 2479-79 - horizontal, vertical shaft up or shaft down, fastening by paws, flange, flange and paws.
In terms of resistance to external mechanical factors, electric motors satisfy the requirements of the mechanical performance group M8 GOST 17516.1-90.
Electric motors can be equipped with position sensors - encoders.
